2 प्राथमिक कुंजी कॉलम के साथ 2 तालिकाओं Ihave। उनकी संरचना है: 

  पब्लिक क्लास एक्स {सार्वजनिक इन्ट आईडी (get; set;} पब्लिक इंट लाइन {get; सेट;}} पब्लिक क्लास वाई [पब्लिक इंट आईडी (get; set;) सार्वजनिक int line {get; set;}}   
 वे एक से एक रिश्ते से संबंधित हैं।  
 कैसे मैं पहले संस्था ढाँचा कोड में 2 तालिकाओं को मैप कर सकता हूं  
 तालिका वाई वैकल्पिक है लेकिन तालिका X की आवश्यकता है।  
 उन्नत में धन्यवाद।   
 
  
  कुंजी  विशेषता के साथ आप कह रहे हैं कि यह गुण आपकी तालिका की चाबियाँ होगा।  विदेशी कुंजी  विशेषता को जोड़ना, एएफ को जानकारी देता है कि किस नेवीगेशन प्रॉपर्टी रिश्तों का प्रतिनिधित्व करती है, यह एक विदेशी कुंजी है अंत में,  स्तंभ  विशेषता ईएफ को बता रही है कि  X  की कौनसी संपत्ति को  वाई  पर एक से मेल खाना चाहिए। अगर मैं आपकी समस्या को गलत समझा, तो कृपया मुझे बताएं ताकि मैं अपना जवाब बदल सकूं।

I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'
